Remove Objects from Legend When You Have Also Used

Question

I've plotted data points and fitted an exponential curve between them using 'fit' in Matlab. The problem is that with the fit-function I got the fitted line I wanted to plot, but also extra markers on top of my regular markers. I solved this problem by plotting the wanted markers on top of the unwanted so that they couldn't be seen. Now to the problem. When I want to show the legends those dots are also in there. How can I remove the markers from the legend without removing the fitted line since both of them are hidden inside the fit-function? Can I stop 'fit' from plotting the unwanted markers? So, I want to remove the blue dot called 'hoff' in the picture below.

Answer 1

You can leave out legend-entries by manually leaving out the handles of the lines, that you dont want to be in the legend. Try this:

%if you plot something, that you want showing up in the legend, save its handle:
h_line = plot(x,y)
%you dont want to show up this line? dont do anything, just plot it:
plot(myMarker)
%then set the legend-> you can add the text for your legend-entries with 
%a cell-array   containing the strings you want to show up:
legend([h_line another_line],{'Text1' 'Text2'})

with the example (see comments) I came to this solution:

close all
X=[1:10];
Y=X*0.5+0.1;
ft = fittype('poly2'); 
f = fit(X', Y',ft); 
ha=plot(f)
hold on
hc=plot(X,Y)
hb=errorbar(X, Y, X*0.1, 'squarek','MarkerFaceColor','k','markersize',5)
hleg1 = legend([ha hc],{'hnh','ghg'});

-> this is just about splitting the plot-command. Hope that helps...

the result should look like this:
